You and your group are members of a safety engineering team with the responsibility for certifving design plans for new amusement park rides. You have been given the plans for a new rollercoaster called the \"Physics Phlyver\". This rollercoaster has a single car. To accelerate the rollercoaster, a small overhead motor runs along a track. The motor pulls a cable that Overhead motar 15 attached to the rollercoaster car. The cable makes an angle with the horizontal and exerts a force on the cable car. There 1s a small, but important, amount of friction between the car and the track. After being pulled by the motor, the train detaches -~ from the cable. It glides down a steep hill and, after ' b travelling a distance along the fairly straight hall, ' v reaches the lowest point with a very great speed. The track at the bottom of the hill follows the arc of a circle with a large radius. At the lowest point, the ' ! passengers will experience a large normal force. If that 5 ' force 1s too large, they will not feel comfortable and R -7 may sustain very minor injuries. 2. After being pulled by the motor, the train detaches from the cable with a speed of 4.8 m/s. It glides down a steep hill (43 to the horizontal) and, after travelling a distance of 79 m along the track, reaches the lowest point with a very great speed. Note that the track material is the same (Y = 0.13) throughout the entire ride. The track at the bottom of the hill follows the arc of a circle with a radius of 29 m. At the lowest point. the passengers will feel a large normal force. If the normal force 1s four times their force of gravity. they will not be comfortable and may sustain very minor injuries. Assume an average person has a mass of 65 kg. A: Pictorial Representation Sketch showing all events, coordinate system, label givens & unknowns with symbols, conversions, describe events o o=
